Title: Off-line teaching method
Inventor: AOKI SHINJI
IPC: G05B19/42
Filed: 1998-06-26
Abstract: Disclosed is an off-line teaching method for correcting a robot model to be used in an off-line teaching system.          Multi-point multi-attitude teaching capable of obtaining the best correcting calculation result of those obtained with a logical robot model as a correction objective is performed by using an off-line teaching apparatus (steps S1 to S5).          Teaching data obtained in the steps S1 to S5 is downloaded from the off-line teaching apparatus to an actual robot as a correction objective (step S6).  Subsequently, the teaching data is revised on the basis of a difference between an actual target point and an operation point of the actual robot based on the teaching data (step S7). After that, teaching data obtained after the revision is uploaded to the off-line teaching apparatus (step S8) to estimate and calculate a correction amount by using the uploaded data (step S9).  Accordingly, it is possible to stably obtain teaching data usable to accurately estimate the correction amount, and it is possible to decrease the number of working steps based on the use of the actual robot.

Abstract: A  hopper  for  the  containment  of  particulate materials   (grain,   sand,   gravel,   etc.)   has  a rectangular solid external wall configuration,  but includes  movable  internal  panels  which  may  be positioned adjacent the inner surfaces of the exterior walls to maximize internal volume, or which may be adjusted to cause particulate material within the hopper to flow into a discharge auger, conveyor, or gate in the hopper floor.  At least one movable panel is  provided,  with  preferably  two  movable  panels disposed on opposite sides of a central discharge opening or passage.  Each of the panels may comprise a single rigid sheet, or may comprise an upper and a lower panel which are hinged together.  Mechanical or hydraulic actuation is provided to shift the panels angularly within the hopper to provide a side wall slope at least slightly greater than the angle of repose of the particulate material therein, to cause the material to flow down the sides of the angled panels and into the discharge passage in the hopper floor.    Another  embodiment  provides  rectilinear movement  of  the  movable  panels.     Yet  another embodiment includes an internal, vertical discharge chute  with  a  lower  discharge  gate  which may be selectively opened to provide bottom discharge of material,  or closed to provide upper discharge as desired.  The various embodiments may be constructed as a wagon for mobility, or may be installed in a permanent, preferably elevated, location for discharge of material into trucks for transport.

Title: Equipment inspection and evaluation system
Inventor: EMOTO HIROSHI
IPC: G06F3/0484
Filed: 1998-07-14
Abstract: An equipment inspecting and evaluating system can be used to inspect and evaluate steam traps by detecting a level of vibrations of each trap and the surface temperature of the housing of that trap. The detected vibration level and temperature are used to determine whether or not steam is leaking through that trap and to what extent steam leakage is. An equipment management system is connected to the inspection and evaluation system by a data transmission cable and receives inspection data of the traps from the inspection and evaluation system. The management system analyzes the received inspection data for computing the number of defective traps, the ratio of defective traps to the entire traps, the loss caused by steam leakage, etc.

Title: A method of pre-pressing fibre material in the manufacture of board products
Inventor: THORBJOERNSSON SVEN-INGVAR
IPC: B27N3/08
Filed: 1997-03-06
Abstract: In a method of pre-pressing a formed web of finely-divided lignocellulosic fibre material prior to pressing the web to a finished state in the continuous manufacture of board material, the fibre material is compacted and pressed successively in an entry section (7) of a pre-press (6) subsequent to being formed into a web (11) and subsequent to a first compression and expansion. The web is compressed in this latter pressing process to a density close to the density of the web after the first compression, whereafter the web is allowed to expand to a controlled limited extent in a pre-press expansion section (9), and thereafter transferred to the finishing press. Steam (A, B) is injected into the web (9) when the web is located in the pre-press (6).

Title: Congestion management in a multi-port shared memory switch
Inventor: GIROUX NATALIE
IPC: H04L12/56
Filed: 1998-11-24
Abstract: A method and system for detecting and controlling congestion in a multi-port shared memory switch in a communications network.  The proposed congestion management scheme implements a local and a global congestion monitoring process.  The local monitoring process monitors the queue depth.  When the queue depth for any queue exceeds a queue length threshold a congestion control mechanism is implemented to limit incoming data traffic destined for that queue. Additionally, the global congestion monitoring process monitors the shared memory buffer and if the traffic thereto exceeds a shared memory buffer threshold a congestion control mechanism limits incoming traffic destined for any output queue which has been exceeding a fair share threshold value.

Patent CA-2281726-A1 (CA)
Inventor: RAMESH RAJARAM
IPC: H04L9/30
Filed: 1998-02-17
Abstract: A fading compensation apparatus and method are provided in which blocks of the analog AM signal (e.g., voice) are time-compressed at a transmitter (10). Gaps in the time-compressed signal (15) are filled with pilot symbols (17) (or similar complex waveforms) having known characteristics, such as predetermined amplitudes. The time-compressed analog AM signal (e.g., SSB or VSB) is transmitted over the fading channel. At an analog AM receiver (20), an estimate (24) of the fading that occurred in the transmission channel is made by observing the amplitude of the received pilot symbols at discrete points in time, and interpolating (26) to determine the amount of fading that occurred across the total transmitted signal. A fading compensator (30) compares the received faded time-compressed signal (28) with the interpolation results (27), and adjusts the amplitude and phase of the received signal accordingly to compensate for the fading that occurred in the transmission channel. The compensated analog AM signal is time expanded (32) and output to a user.

Inventor: PEEBLES ANN L
IPC: H01Q1/28
Filed: 1999-12-29
Abstract: An antenna system comprising a feed array, a subreflector and a main reflector which are oriented to define a offset gregorian antenna geometry.  The feed array is comprised of a plurality of separate feeds which are aligned on a predetermined contour. Each feed array is coupled to a feed network which acts to combine the illumination beams of clusters of a preselected number of feeds to produce a plurality of composite illumination beams. Each composite illumination beam is directed to be incident upon a separate predetermined location on the subreflector which directs the composite illumination beams and directed towards the main reflector. Each composite illumination beam is reflected by the main reflector in a preselected direction so that each composite illumination beam forms an antenna beam that impinges a predetermined coverage area on the Earth. Each antenna beam defines a separate coverage cell in the coverage area, wherein the position and orientation of the feeds, the subreflector and the main reflector provides antenna beams over a full Earth field of view coverage area where each antenna beam is approximately symmetrically shaped.

Abstract: A method of raising the transmission hardware carried by a utility pole having a base end with a ground foundation supporting the pole in upright position, without disturbing the pole foundation or disconnecting the cables, includes the steps of securing opposed, circumferentially spaced elongate pole support members to extend upwardly along the pole and severing the pole to define a first pole supported by the pole foundation and a second pole supported by the first pole; fixing the support members to the first pole and slidably banding them to the second pole; raising the second pole above the first pole to a level remaining below the upper ends of the support members; and fixing the lower end of the second pole within and to the upper ends of the support members at a spaced distance above the first pole. The method further contemplates the releasable securement of ladder steps to at least one of the support members to provide ready access for carrying out some of the method steps.
